And then there are fenix e05r and e09r which are hold to turn off, but if you hold just a bit longer you get burst which is quite bright and painful/completely blinding in low light scenario.
It is next level of bad… as much as i like the lights otherwise it makes them borderline-unusable…
I want to say being made/assembled in China but I own some Fenix and LED Lensers. I’d spend more and go way out of the way to gte made in USA/EU though.
Built-in/non-removable batteries that prohibit a quick on the go cell swap. I only have one light with a proprietary cell but it will take normal cells too (Olight 16340…proprietary only for the mag charging)…even if a cell is proprietary at least if it can be swapped then you aren’t stuck without a light waiting for recharging. I don’t like the recent trend of proprietary protected cells where standard (cheaper, often better) cells can’t be used.
Strobe in main mode rotation, although thankfully that’s nearly a thing of the past except with the cheapest lights.
I’m getting to where I might pass on lights that use a solid post contact on the driver instead of a spring, but it depends on the light. Sadly that trend has really taken hold and doesn’t seem like it will go away since it also allows cheap implementation of reasonably effective reverse polarity physical protection. Sure is a pain with larger/heavier cells sometimes, though.
I don’t mind it because sometimes I will use it if it’s there but I can do without. I haven’t found one that charges properly yet. Its either overcharge/undercharge or both. Like there will be some crappy button top that you know you have to charge at 500mah and then you plug in the usb-C cable and immediately sending 2.4amps but then it never charges past 4.1V no matter what charger you use. And some that don’t seem to have a real CC charging stage more like stepped ramping where it just drops in 400mah increments.
1. Next-mode memory or lack of memory.
2. Long memory catch 2 to 8-second memory catch.
3. Visible PWM.
4. Double-click for turbo.
5. Anduril or unregulated.
6. Head-heavy.
7. Multiple level step-downs.
8. Reverse clickies.
9. Multiple switch activation so that the tailcap has ONLY turbo no matter what.
10. Any flickering at all.
